      Abstract
      Madu mempunyai senyawa chrysin yang diketahui dapat berperan dalam proses maskulinisasi beberapa jenis ikan melalui penghambatan aromatase. Penelitian ini bertujuan untuk mengevaluasi pengaruh penggunaan madu dalam proses maskulinisasi larva ikan nila kekar. Proses maskulinisasi dilakukan dengan metode perendaman pada awal pemeliharaan larva ikan nila kekar dengan empat perlakuan dan tiga ulangan, yaitu: 1) tanpa perendaman (KN), 2) perendaman menggunakan hormon 17a-metyhtestosteron sebagai kontrol positif (KP), dan perendaman menggunakan madu dengan 3) dosis 5 mL/L (M5) dan 4) 10 mL/L (M10). Hasil penelitian menunjukkan bahwa pemberian madu dengan dosis 5 mL/L dapat menghasilkan ikan dengan persentase kelamin jantan tertinggi 78.25%, perlakuan KN mendapatkan hasil terendah yaitu 39.50%, tingkat kelangsungan hidup tertinggi dan terendah didapati hasil dari perlakuan M5 dan KP sebesar 88% dan 62.05%, pertumbuhan bobot mutlak tertinggi pada perlakuan M5 43%, dan terendah dari hasil perlakuan KN 3.8%, laju pertumbuhan spesifik dengan hasil tertinggi ada pada hasil perlakuan KP 40.7%, dan terendah pada perlakuan M5 30.0% hari-1. Berdasarkan hasil penelitian ini maka dapat disimpulkan bahwa perlakuan M5 menghasilkan jumlah persentase ikan kelamin jantan yang tinggi.
       
      Honey contains the compound chrysin which is known to play a role in the masculinization process of several types of fish through inhibiting aromatase. This study aims to evaluate the effect of using honey in the masculinization process of tilapia larvae. The masculinization process is carried out using the stocky tilapia larvae with size of 0.1 cm, namely: 1) without immersion (KN), 2) using hormone 17a-methystosterone (KP), and using honey with 3) doses 5 mL/L (M5) and 4) 10 mL/L (M10). The results of the research showed that giving honey at a dose of 5 mL/L could produce fish with the highest percentage of male sex, 78.25%, KN the lowest percentage 39.50%. The highest and lowest survival rates from the M5 and KP of 88% and 62.05%, the highest weight growth was in the M5 43%, and the lowest from the KN results 3.8%, specific growth rate with the highest in the KP results 40.7%, and the lowest in the M5 30.0% day-1. Based on the results of this research, that the M5 produces a high percentage of male fish.
